sPncIrIcA'TIoN forming part of Letters Patent No. 660,869, dated octetsso, 1906.

7 Application filed March 16, 1898- To all whom it ma concern: p

I Belt known that I, CARROLL B. ROGERS, of

El Paso, in the county of El Paso and State of Texas, have invented anew and Improved Slime-Jigging Machine, of which the following is afull, clear, and exact description.

This invention relates to improvements in slime-jigging machines; andthe object is to 2, showinga slime-jigging machine embodying myinvention. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is asection on the line 3 3 of Fig. 1. Fig. 4 is a plan View showing theconstruction of a screen-frame employed. Fig. 5 is a section on the line5 5 of Fig. 4. Fig. 6 is an elevation of a gate and latch employed, andFig. 7 is asection through the line '7 7 of Fig. 6. V

Referring to the drawings, 1 designates a tank of any suitable size andconstruction and having vertical side walls. This tank is provided witha bottom portion, which consists of a suitable horizontal section,'(clearly indicated in the drawings,) of an intact substantially V-shaped base 2, having a'continu ous and uniform downward inclination fromsaid horizontal section to the bottom of the opposite vertical side wallof the tank, and of, suitably-shaped upwardly-flaring side walls, thelatter forming with said base a chute-like structure the internaldimensions of which continuously decrease from the upper to the lowerextremity thereof. The tank 1 is further provided with an outlet 3,normally closed by a gate 4, held from movement by internal pressure bymeans of a latch 5. The latch 5 consists of a bar secured to the tank orto its frame and having an outwardly and downwardly turned portion toengage against the outer side of the gate-handle. This will allow anupward movement of the gate, but

gitudinal strips 16 and cross-strips 17. frame rests on ledgesl8,secured to the inner ,wall of the tank 1 and to the partition 6. For

will preventits being forced outward. Extending across the'tank 1, aboutmidway of its front and rear walls,'is a partition 6, the bottom ofwhich terminates at a point somewhat short of'the base 20f thetank-bottom portion and somewhat below the plane of the horizontalsection of said bottom portion. Operating in a chamber at one side ofthe partition 6 is a plunger 7, which has a rod conplunger.

In the compartment opposite thatoccupied by the plunger 7.is a screen15. This screen is designed to be stationary, and therefore it ismounted on a metal frame consisting of lon- This convenience infastening the screenmaterial in position I provide the several stripsforming the screen-frame with longitudinal channels 19,-in which woodenstrips are seated. The screen material 15 is secured to the strips 20 bymeans of nails 21, which are preferably of copper, as copper nails arenot liable to corrode. 7

Above the screen 15 the tank 1 hasa valvecontrolled communication 22with a concencrate-receiver 23. The valve for controlling the outlet 22consists of a plate 24, movable in guides 25 This concentrate-receiver23 has a pipe 26 for discharging the heavier particles of concentratesinto a lower concentratereceptacle 27, which, as here shown, is designedto be placed under the tank 1 and is removable therefrom. The pipe 2613provided with a suitable valve 26 At the front of the tank 1 is a hopper28 for the material tobe treated. The material inserted through thishopper 28 will fall onto the screen 15, and at the opposite side is abridge-wall 29, over which the tailings or other refuse may fall into atailings-receptacle 3 0. This ta'ilings-receptacle is arrangedexteriorly to the tank 1 at the bridge-wall 29 and is capable ofmaintaining the level of the water therein and within the tank propernormally above said bridge-wall. It is also provided with avalve-controlled outlet 31, and the valve for this outlet is designed tobe so regulated as to only take off the gangue, causing the water andlight slime to be backed up, doing away with a current of water asordinarily used and which carries oif fine particles of minerals. At theupper portion of the tank 1 and at the rear end thereof is anoverflow-plate 32 for the discharge of any excess of water in the tank.The tank bottom portion hereinbefore described and the arrangement ofthe partition 6 with respect to said bottom portion constitute essentialfeatures of my invention, the same serving in practice to so control ormodify the currents or pulsations created in the wash-water within thetank 1 through the reciprocating movements of the plunger-7 as to insurea highlyeffective application of said washwater to the ore-bed on thescreen 15 in the screen-compartment of the tank, and in this connectio'nthe horizontal section of said bottom portion serves at each downwardthrust of the plunger 7 to bafile the Wash-water within theplunger-compartment of the tank and abruptly divert the same laterallyto and against the partition 6, which in turn baflies said water, and byreason of the lower extremity thereof terminating at a point somewhatbelow the horizontal plane of said horizontal bottom section abruptlydiverts said water downward upon a portion of the inclined surfacespresented by said bottom portion, from which latter point said watermakes its Way chiefly to the opposite vertical side wall of the tank 1,and thence to the screen 15 by way of the screen-compartment of thetank. These abrupt bends in the course of the washwater from theplunger-compartment of the tank to the screen in the screen-compartmentof the tank, brought about, as they are, by the peculiarly-formed partswhich I employ, serve to insure a highly-effective application of thewash-water to the ore-bed on the screen 15.

In operation the slime or ore to be treated will be placed upon thesieve substantially to the level w. Then the tank is to be tilled withwater through the supply-pipe 33, after which the plunger'7 is to be putin operation. vertical movements of the plunger 7 will agitate the waterin such manner as to give a pulsating motion to raise the ore-bed on thesieve and allow the bed of ore to flow by its own gravity, the heavyparticles of mineral, &c., sinking to the bottom and the light ganguebeing forced on top. The chlorid and fine valuables which remain insuspension in the water may be caught by skimming the light topoverflow, which may be regulated as desired. A portion of the valuablemineral will fall into the water below the sieve, and lighterportionsthat is, portions too light to remain in suspension or to riseto the top of the water-will pass through the The opening 22 into thereceiver 23. The floated tailings will pass over the bridge 29 into thetailings-receptacle 30, from which they may be removed, as beforedescribed, and the concentrates falling into the chamber or space belowthe sieve and to the bottom thereof may be removed as desired throughthe outlet 3.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- 1.
